to mods: was unable to get link of image from url.

Yes, sometimes this is not possible

In these cases, there is even more reason to try and come up with an alternative logo by looking in Google.
Please do this in future

Also name your request with details of at least one of the URLs requested so it is an easy matter to differentiate your request from others.

many thanks

Logo (small) from wiki

seems there was also cognizance 2009

please see here (for logo information only)

this logo would seem to be possibly related too to cognizance 2009, but does not contain the current logo, so is not that relevant, but is an interesting logo nevertheless:
